How to implement a diskless system and how to do a diskless system

That is, the computer can enter the operating system without a hard disk. The implementation of the principle of the network card contains a boot function, which can be connected to a computer with an operating system image, and the operating system image is provided by other computers.

1. Server-side detailed settings:

Win2k server version example).

1. Server operating system installation: install Win2K Server version of the operating system, it is strongly recommended to use a separate 40G hard disk to install the system, divided into three areas: C disk system, D disk to store workstation image package, etc., E disk to store C disk clone backup and common software drivers, etc.; During the installation process, in addition to setting the number of simultaneous connections per server:

is n (n is greater than the actual number of workstation computers)", other defaults can be!

4. Create a super user: remember to enable the "guest" user account; Then create a user, e.g. create a username called vod, and grant the most senior administrator privileges! This user is used for work diskless logins.

There are a few steps to pay attention to without a disk.

In fact, it is easy to make mistakes in these steps:

1. After the client master disk is done, install the Ruiqi client (enter the IP address of the server) and enter the [Management Tools] > server of the server system.

service] to restart them once.

"Diskless XP Auxiliary Service" and "Diskless XP Data Service";

2. Unplug the hard disk, boot it from PXE, and enter the client IP and client name.

3. Close the client, then select the template workstation information you just joined on the server, press the "superuser" button, and set it as a superuser.

4. Set it to hard disk boot again, set a fixed IP, and restart it after setting.

5. After the workstation is restarted, enter the "Disk Management" in [Management Tools] >Computer Management], and a new hard disk (i.e., network disk) should be visible in the disk manager, partitioned and formatted in the normal way.

6. Note: Do not set the network disk to a "dynamic disk", but to a "basic disk". And the capacity of the first partition should not be greater than 8192M (i.e. 8G).

7. Run the client's "Sharpstart Diskless XP Upload Tool", and the software will automatically check the system and network disks in the hard disk, and determine the source disk and target disk that need to be uploaded

8. After the upload is over, close the client, unplug the hard disk, and turn it on again, and the client should be able to boot normally and enter the operating system.

The so-called diskless system is that all the work in the network does not install hard disks, and all are started through the network server, such a network is a diskless network, and these workstations are called diskless workstations. It makes use of the technology of virtual hard disk, so as to achieve the function of free management and maintenance of workstations. Administrators in charge of network management: Yes"Management and maintenance"It should be understood that the main job of a network administrator is to ensure that a network can operate normally.

If there is something wrong with the workstation in the network, the machine cannot be turned on, the network cannot be connected, or the software in the network needs to be upgraded, then the network administrator will be busy, and he will be responsible for adjusting each machine, installing new software, and even reformatting, partitioning, and installing the system on the hard disk of each machine. Maybe it won't be long before the system is accidentally destroyed by students, so it is cumbersome installation, debugging, etc., not to mention the trouble, but also to delay the work and affect the normal use of users.

As a result, a new network structure: diskless networks emerged. One of the original intentions of diskless networks is to reduce the cost of workstations, but it is mainly for the convenience of management and maintenance.
